Question

A cookie can give one person a sugar rush while barely affecting another person, a new study finds, indicating that a food’s glycemic index（血糖指数）is in the eater.

People’s blood sugar rises or falls differently even when they eat the exact same fruit, bread, deserts, pizza and many other foods, researchers report. That suggests that diets should be tailored to individuals’ personal characteristics.

The researchers made the discovery after fitting 800 people with blood glucose （血糖）monitors for a week. The people ate standard breakfasts supplied by the researchers. Although the volunteers all ate the same food, their blood glucose levels after eating those foods varied dramatically. Characteristics and behaviors such as body mass index, sleep, exercise, blood pressure, cholesterol levels and the kinds of microbes（微生物） living in people’s intestines are associated with blood glucose responses to food, the researchers conclude.

Those findings indicate that blood sugar spikes （血糖尖峰）after eating depend not only on what you eat, but how your system processes that food.

A team led by a biologist created a computer algorithm(计算程序) that predicted how much a person’s blood sugar would rise or fall after eating a certain food. When testing on a new group of 100 people, the algorithm correctly predicted the response about 70 percent of the time.

A third group of 26 participants were then given personalized meals. The computer algorithm analyzed each person and then picked diets for 12 of them. A nutritionist chose a “good” and “bad” diet for the remaining participants. Good diets were ones that minimized blood sugar spikes after eating. Bad diets sent blood sugar skyrocketing. The diets contained the same amount of calories. It turned out that foods on the “good” diet for one person were sometimes on another participant’s “bad” list.
